Abstract (en)
[origin: EP0414941A1] For an operator-friendly drive, which is immune to faults and of compact dimensions, for positioning an air distribution flap in a motor vehicle air conditioning and/or ventilation unit with an electric motor (4) which can be made to follow in accordance with a manipulated variable, which can be predetermined by a rotary control knob (1), until a corresponding position of the air distribution flap is reached, a code disc (2 and 3 respectively) with binary encoded sliding tracks are assigned both to the rotary control knob (1) and to the power-output of the air distribution flap (power-output shaft 44 of the electric motor), the sliding track tap-offs of which tracks are connected to a comparator (5) via which the electric motor (4) which is being made to follow is supplied with current via its feedlines (51, 52) until both code discs (2 and 3, respectively) are balanced. <IMAGE>
